12mm × 12mm × 7.3mm Tactile Push Button Switch with Round Cap (2 Pieces)

The 12mm × 12mm × 7.3mm Tactile Push Button Switch with Round Cap (2 Pieces) is a compact and reliable momentary push button switch designed for use in electronic circuits, embedded systems, control panels, and DIY electronics projects. This pack includes two tactile push button switches along with matching round button caps, providing a comfortable and easy-to-press interface for manual input applications.

A tactile push button switch is a momentary normally open (NO) switch, meaning the electrical contacts remain open until the button is pressed. When the button is pressed, the contacts close and allow current to flow through the circuit. Once the button is released, an internal spring mechanism automatically returns the switch to its original position, opening the circuit again. This momentary operation makes tactile switches ideal for applications where temporary user input is required.

Each switch measures 12mm × 12mm × 7.3mm, making it suitable for compact electronic designs while still providing a large enough surface for comfortable operation. The included round cap fits securely onto the switch actuator, improving usability, appearance, and user experience.

The switch is designed with through-hole PCB mounting pins, allowing secure installation on printed circuit boards (PCBs), prototype boards, and development boards. It can also be easily integrated into breadboard-based prototypes with appropriate spacing. The durable internal contacts provide reliable switching performance with consistent tactile feedback and a distinct click action that confirms successful button activation.

These tactile push buttons are widely used in Arduino projects, Raspberry Pi projects, embedded systems, robotics, consumer electronics, industrial control equipment, menu navigation systems, home automation devices, electronic instruments, and educational electronics projects. Their dependable operation and long mechanical life make them suitable for both hobby and professional applications.

Whether used as a reset button, menu selection key, mode selector, user input button, or control switch, the 12mm Tactile Push Button Switch with Round Cap offers reliable performance, easy installation, and excellent durability for a wide variety of electronic applications.

Working Principle

The tactile push button operates as a momentary normally open switch.

• In its normal state, the internal contacts remain open.

• Pressing the button closes the contacts, allowing electrical current to flow.

• Releasing the button allows the internal spring to reopen the contacts.

• The switch provides a noticeable tactile click that confirms successful operation.
